Computed Tomography and Magnetic Resonance Imaging of the Thyroid and Parathyroid Glands.

Computed tomography (CT) and magnetic resonance imaging (MRI) are advanced imaging modalities that are not typically utilized as part of the initial evaluation of thyroid and parathyroid pathology. However, both modalities have applications in complex cases, particularly in the reoperative setting and in operative planning for initial or recurrent carcinomas. As part of a multimodal approach, CT and MRI can increase the successful preoperative localization of abnormal parathyroid glands.
